Thanks!!!!

oh yeah you to

Don't I too?

2/-3 = -.67

you rock at this tiddla

60 is the answer.

45/.75 = 60

-3n + 9 < 6n + 18

Add 3n to both sides:

         9 < 9n + 18

Subtract 18 from both sides:

        -9 < 9n

Divide both sides by 9:

        -1 < n     or     n > -1

Very great indeed!  I'm impressed!

Thank you...

To simplify this, you need a common denominator.

Since 4x + 4y  =  4(x + y), a common denominator is:  4(x + y)(x - y)

Solving:  [ 3/(4(x + y)) ] · [ (x - y)/(x - y) ]  +  [ 1/(x - y) ] · [ 4(x + y) ]/[ 4·(x + y) ]

=  [ 3(x - y) ] / [ 4(x + y)(x - y) ]  +  [ 1·4(x + y) ] / [ 4(x + y)(x - y) ]

=  [ 3(x - y) + 4(x + y) ] / [ 4(x + y)(x - y) ]

=  [ 3x - 3y + 4x + 4y ] / [ 4(x + y)(x - y) ]

=  [ 7x + y ] / [ 4(x + y)(x - y) ]

nice job tiddle you did great

Good try though

I know........

No problem

Why thank you.

Good job Tiddle

Too late dude

Me? I'm not mad. 

No I was just about to answer.

There is no single answer.

For instance:  x = 16, y = 0, z = 0

                    x = 4, y = 4, z = 0

                    x = 25/9, y = 4, z = 1/9

etc. 

There is an infinite number of possible answers.
